Lexical ambiguity presents one of the most intractable problems for language processing studies and, not surprisingly, it is at the core of research in lexical semantics. Originally published as two special issues of the Journal of Semantics, this collection focuses on the problem of polysemy, from the point of view of practitioners of computational linguistics.

Computational Lexical Semantics is one of the first volumes to provide models for the creation of various kinds of computerized lexicons for the automatic treatment of natural language, with applications to, among other things, machine translation, automatic indexing, database front-ends, and knowledge extraction. It focuses on semantic issues, as seen by linguists, psychologists, and computer scientists. Besides describing academic research, the book also covers ongoing industrial projects.

A primary problem in the area of natural language processing has been semantic analysis. This book looks at the semantics of natural languages in context. It presents an approach to the computational processing of English text that combines current theories of knowledge representation and reasoning in Artificial Intelligence with the latest linguistic views of lexical semantics. The book will interest postgraduates and researchers in computational linguistics as well as industrial research groups specializing in natural language processing.

This book explains how to build Natural Language Generation (NLG) systems--computer software systems that automatically generate understandable texts in English or other human languages. NLG systems use knowledge about language and the application domain to automatically produce documents, reports, explanations, help messages, and other kinds of texts. The book covers the algorithms and representations needed to perform the core tasks of document planning, microplanning, and surface realization, using a case study to show how these components fit together. It is essential reading for...

In this particularly well written volume Graeme Hirst presents a theoretically motivated foundation for semantic interpretation (conceptual analysis) by computer, and shows how this framework facilitates the resolution of both lexical and syntactic ambiguities.

This book is concerned with the machine-based generation of natural language text and presents a formal analysis of problems, which in the main have previously only been approached descriptively. In the process of producing discourse, speakers and writers must decide what it is that they want to say and how to present it effectively. Kathleen McKeown's main concern is to identify and formalise principles of discourse so that they can be used in a computational process. The text generation theory she describes has been embodied in a computer program, TEXT, which, given a question, can produce...

This book is an investigation into the problems of generating natural language utterances to satisfy specific goals the speaker has in mind. It is thus an ambitious and significant contribution to research on language generation in artificial intelligence, which has previously concentrated in the main on the problem of translation from an internal semantic representation into the target language. Dr. Appelt's approach, based on a possible-worlds semantics of an intensional logic of knowledge and action, enables him to develop a formal representation of the effects of illocutionary acts and...

This innovative book develops a formal computational theory of writing systems and relates it to psycholinguistic results. Drawing on case studies of writing systems around the world, it offers specific proposals about the linguistic objects that are represented by orthographic elements and the formal constraints that hold of the mapping relation between them. Based on the insights gained, it posits a new taxonomy of writing systems. The book will be of interest to students and researchers in theoretical and computational linguistics, the psycholinguistics of reading and writing, and speech...
